duty. In the iron ore industry, most of the machines are found in pellet feed applications. However, there are a few notable examples where HPGRs are used for coarse iron ore grinding in Chile, Mauritania and the USA. The first large scale attempt at applying HPGRs to harder and more abrasive copper and gold ores was in 1996 at Sierrita.

AG mills crush the ore without the need for iron or steel grinding media. They are used when the ore is hard enough for the tumbling ore to grind itself. In SAG milling, ∼ m 3 of 13 cm diameter iron or steel balls are added into the mill per m 3 of ore (, 15 vol.% "steel") to assist grinding. SAG mills are much more common.

This is particularly true for some of the secondary grinding (primary ball mills) of magnetic iron ores. In magnetic iron ore grinding, the silica levels are continually being decreased from crushing to rod milling to ball milling by intermediate concentration steps. Subsequently, the wear environment becomes progressively less abrasive.

Tumbling mills (ball mills, rod mills, etc.) utilize both continuouspressure and impact mechanisms. Blasting, explosive shattering, and decrepitation (firesetting) are tensiontype crushing operations; all three are relatively unimportant as crushing operations, although blasting is, of course, preeminently useful in rock excavation.
